Ordered own kind to profess ignorance (1,4,4)

I believe the answer is:

i dont know

'profess ignorance' is the definition.
(phrase used to express ignorance)

'ordered own kind to' is the wordplay.
'ordered' indicates an anagram.
'own'+'kind'+'to'='ownkindto'
'ownkindto' anagrammed gives 'I DONT KNOW'.

I've seen this clue in The Guardian.
